Recently, bowtie-shaped apertures have received significant attention due to their extraordinary ability to generate dramatic field enhancement and light confinement in nanometer scale. In this article, we investigate both experimentally and theoretically ...

We present a compact and multi-resonant aperture system supporting large local electromagnetic fields, which is highly advantageous for applications demanding high signal-to-noise ratio. The system is composed of subwavelength H-shaped apertures with exten ...
We experimentally demonstrate that elevating polarization-insensitive nanoring antennas on nanopedestals enables high surface enhanced infrared absorption (SEIRA) signals. This is due to larger and accessible nearfields offering better overlap with biomole ...
